Valprovia Teams Center Release Notes

Release v2.26.12

(25.08.2025)

Introduction

This focused release strengthens data integrity and user experience by implementing comprehensive validation rules for Document Set configurations. We've established clear guardrails to prevent configuration errors and ensure SharePoint compatibility across all workspace deployments.

Enhancements

🛠️  Enhanced Document Set Field Validation:
Implemented robust validation rules for Document Set internal names and display names to ensure SharePoint compatibility and prevent provisioning failures. The internal name field now enforces strict character restrictions, prohibiting special characters (" # % * : < > ? / \ |) and periods at the beginning or end of values, while both fields respect the 255-character limit. Display names have been liberalized to accept all special characters while maintaining length constraints. These enhancements provide immediate user feedback with clear, actionable error messages, preventing downstream provisioning issues and ensuring seamless Document Set deployment across all Teams workspaces.

------------------------------------------------------------

Release v2.26.11

(08.08.2025)

Introduction

This patch release addresses workflow integrity issues affecting bulk operations, notification systems, and identity management. We've prioritized fixing edge cases that impact day-to-day administrative operations and team collaboration scenarios.

Enhancements

🛠️ OneNote Tab Naming Consistency:
Resolved an issue where custom-named OneNote tabs were unexpectedly reverting to default "Notes" naming during bulk template updates. This fix ensures that administrators' intentional naming choices are preserved across template versioning and bulk operations, maintaining consistency in workspace configurations and preventing confusion for end users navigating channel resources.

🛠️  Nested Group Membership Optimization:
Corrected the provisioning behavior for nested group members to prevent redundant individual user additions. The system now properly recognizes nested group hierarchies, eliminating duplicate membership requests and reducing synchronization overhead while maintaining accurate group-based access control.

🛠️ Channel Guest Notification Enhancement:
Fixed a Logic App workflow issue that was generating empty notification emails when multiple users were added as channel guests simultaneously. The improved logic ensures that all notification emails contain appropriate content, enhancing communication reliability and providing recipients with meaningful invitation details.

🛠️  Guest Approval Workflow Restoration:
Resolved a identity resolution issue where new guest approval requests were failing due to uninitialized user IDs. The fix ensures workspace owners receive proper approval notifications for guest invitations, restoring the complete approval workflow and maintaining security governance for external collaboration.

------------------------------------------------------------

Release v2.26.10

(05.08.2025)

Introduction

This quality-focused release enhances Teams Center's cross-tenant collaboration capabilities and search functionality. We've refined error handling, request processing accuracy, and data type compatibility to deliver a more robust and intuitive user experience.

Enhancements

🛠️ Improved Trusted-Tenant User Search Experience:
Refined error handling for shared channel guest searches to provide graceful degradation when querying non-trusted tenant users. This enhancement replaces internal server errors with appropriate user feedback, ensuring administrators receive clear guidance when searching across tenant boundaries and improving the overall shared channel management experience.

🛠️  Private Channel Member Removal Accuracy:
Corrected the request status reporting mechanism for internal guest removal from private channels. While the removal operation was executing successfully, the system now accurately reflects completion status, eliminating false failure notifications and providing administrators with reliable confirmation of membership changes.

🛠️  Enhanced Internal Guest Search Compatibility:
Resolved a critical data type mismatch in the Microsoft Graph API filter clause that prevented successful searches for internal guests. The fix ensures proper handling of boolean values in string extension attributes, restoring full search functionality and enabling administrators to efficiently locate and manage internal guest users across the platform.

------------------------------------------------------------

Release v2.26.9

(11.07.2025)

Introduction

This focused release addresses a collaboration feature to ensure seamless integration between Teams and OneNote. We've prioritized restoring full functionality to enhance the day-to-day productivity experience for all users.

Enhancements

🛠️ OneNote Tab Integration Restoration:
Resolved a provisioning issue that prevented OneNote tabs from loading correctly within the Teams client interface. This fix ensures that custom-named OneNote tabs, particularly those renamed from the default configuration, now open reliably within Teams channels. While OneNote notebooks remained accessible through SharePoint and direct links, this enhancement restores the native in-Teams experience, eliminating workflow disruptions and ensuring consistent cross-platform collaboration capabilities.

------------------------------------------------------------

Release v2.25.0

(31.01.2025)

Introduction

This release introduces significant enhancements in security and user lifecycle management. With the advanced security enhancements and improvements in external user management, organizations can better control access to their collaboration spaces.
